1, prepare the container: choose a transparent, non-leakage water basin, sterilized and dried.2, for hydroponics: the hollow cabbage stalks into the water, in an upright state.3, breeding environment: move the hollow cabbage to a place with good light, so that the plant receives sunlight.4, water management: the interval of 1-2 weeks to the hollow cabbage to change the clean water of the river.

1, prepare the container

Before hydroponics cabbages, you need to prepare a water basin with a depth of about 20-40 centimeters, clean and disinfect the container, and then fill it with two thirds of the water, be careful not to use tap water for breeding, or else the cabbages' root system will rot.

2, carry out hydroponics

Hydroponics of cabbage, the plant should be cleaned, and then put it into the water, so that the stalks present an upright state, can not float on the water surface, to avoid the root of the cabbage can not absorb water, the phenomenon of poor growth.

3, breeding environment

Later maintenance of cabbage, be sure to control the temperature at about 20 degrees Celsius, the plant likes a warm environment, if the temperature is lower than 10 degrees Celsius, the rhizomes will begin to yellow, and to ensure that there is a soft light, to promote the growth of cabbage.

4, water quality management

Hydroponic cabbages have high requirements for water quality, need to change the water every 1-2 weeks, when the weather is hot, it is best to change the water to the plant at intervals of 3-4 days, and change the water to the cabbages to apply diluted liquid fertilizer.
